SHINGLE-MACHINE.

Specification of Letters Patent.

Patented Dec. 28, 1909.

Application filed August 31,1907. Serial N0. 390,923.

To all whom it may concern:

Be itknown that 1, CHARLES JOHN BRANDT, a citizen of the United States,residing in the town of VVindemere, in the county of Pine and State ofMinnesota, have invented a new and useful Shingle-Machine, of which thefollowing is a specification.

The present invention has reference to improvements in shingle machines,and it aims, primarily, to provide an exceedingly simple and efficientmachine of that nature designed especially for the use of lumber dealersin the timber sections of the country.

More specifically, it is the object of the in vention to provide aportable shingle machine which may be readily moved from place to placeover ordinary roads without necessitating its being previously takenapart, and which will cut rough blocks,

round or square, of different dimensions, with but little waste ofmaterial, and will require but a single man to operate it and a singlehorse for power.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, in which corresponding parts are designated bythe same reference characters throughout the several views.

Of the said drawings, Figure 1 is a perspective view of the completemachine. Fig. 2 is a fragmental bottom plan view of the sweep. Fig. 3 isa fragmental section taken vertically through Fig. 1. Fig. at is atransverse section taken through the sweep, and illustrating thearrangement of the knife and shoe, a partially-shaped block beinglikewise shown in said figure.

The frame work of the machine illustrated in the drawings, consists,primarily, of a series of upright posts A, (ten being shown in thepresent instance), arranged at equidistant intervals apart from eachother and from the center of the machine, the posts being connectedtogether adjacent their lower ends by a metal band N, and adjacent theirupper ends by a pair of similar bands D and E arranged in spacedrelation to each other.

The band N is secured by means of bolts Q2 to the posts, against whoseouter faces it is disposed, while the band D, which is likewise disposedagainst the outer faces of the posts is secured to the latter and to theposts and connected with the inner band E by means of yoke-shaped boltswhose stems pass through registering openings formed in said bands an inthe posts, the arms of said bolts receiving the outer ends of the radialbraces G. The inner ends of these braces rest upon the enlarged centralportion of a diametrically arranged brace B, two of the bolts Q havingtheir arms spaced sufliciently far apart to receive the ends of thebrace in addition to those of the two alining radial braces C which restupon said brace throughout their entire lengths. The several posts arestill further braced by a series of inclined metal straps F, perforatedat opposite ends and arranged adjacent the inner faces of the posts, thebolts 9 passing through the perforations in the lower ends of thestraps, and the shanks of the bolts 9 through the perforations in theupper ends thereof, as shown in Figs. 1 and 3.

The inner ends of the braces G, as above stated, rest upon the centralportion of the braces B, to which portion they are bolted, the boltspassing through perforations formed therein and in a metal plate Q,which rests upon said ends. This plate is further provided with acentral perforation through which loosely passes the stem of a verticalyoke-shaped bolt J, the lower end of said stem having a perforationarranged to receive a split pin S, there being interposed between thepin and the under face of the brace B, an annular washer R which islike-- wise carried by the bolt stem. The bolt J forms a pivot for thesweep U, whose inner end fits between the arms of the yoke portion ofthe bolt and is supported by a horizontal bolt Y, which passes looselythrough an opening formed transversely of the sweep end, the ends ofthis bolt extending through openings formed in the yoke arms. By reasonof this construction, it will be apparent that the sweep is capable ofbeing swung in a horizontal plane through a complete circle, and alsothat during such revolution it is capable of swinging upwardly uponthebolt Y as a pivot, this upward movement being efiected automatically bymeans of a forwardly and upwardly inclined shoe V formed by a metalstrap bent upon itself and having its ends disposed against and securedto the upper and lower faces of the sweep. The direction of revolutionof the sweep is clockwise.

The posts A project slightly above the upper edges of the bands D and E,and the portions of said edges between the pairs of posts are arrangedto support the blocks from which the shingles are subsequently cut.These blocks are held against displacement in such position by means ofplatesL and levers M, there being a plate secured to the top of eachpost and a lever pivoted adjacent its upper end in each of the equaldivisions of the annular space between said bands, the divisions beingcaused by theprojection of the post ends through said annular space.

Each plate has its right hand side edge (with reference to Fig. 1)serrated, the teeth being designed to bite into the adjacent end of theblock which rests upon the bands to the right thereof, the other end ofthe block being engaged by the teeth formed upon the upper end of theadjacent lever M, the toothed end of which is curved toward the plate.It will be plain, therefore, that the pivotal mounting of the leverspermits them to force the blocks into engagement with the toothed edgesof the plates, the levers being retained in adjusted position by meansof racks 79 secured to the right hand side faces of the posts, the lowerportions of the levers being arranged for engagement with the racks, asshown in Fig. 1.

The cutting of the shingles is effected by a knife X, secured to theunder face of the sweep and set at an angle to the axis thereof, theshoe V being located directly opposite the knife. Directly above theknife, which is inclined slightly downward so as to dispose its cuttingedge below the lower edge of the sweep, there 'is formed in the sweep aslot X, the upper face of the sweep having secured thereto a plate Zprovided with a tongue Z which extends into said slot, the tongueforming a guide along which the cut shin les are arranged to travel. Asthey issue from the slot, the shingles are deposited by the operator ofthe machine in a box I attached to the rear edge of the sweepintermediate the ends thereof, the rear wall of the box being formedwith a vertical slot 1, the provision of the slot permitting theoperator to remove all of the shingles at once from the box by insertinghis hand through the slot and raising up the mass of shingles bodily.The knife is prevented from coming into contact with the upper edges ofthe bands D and E, after theblocks have been almost entirely consumed,by means of a metal plate W secured to the under face of the sweep andarranged to contact with the upper edge of a metal ring K bolted to thebraces C and arranged concentrically of said bands, such contact takingplace when the consumption ofthe blocks reaches a certain point.

The machine, as a whole, is held in stationary position upon the groundby means of a'series of hooks 0, whose bent upper ends are arranged forengagement with the lower band N, thepointed lower-ends of the hooksbeing inserted in the ground.

When the machine is to be moved from one point to another, it is onlynecessary to press upwardly uponthe lower edges of the bands D and E,whereupon the hooks will be withdrawn from the ground. The sweep carries at its extreme outer end a hook T arranged for engagement with theharness of the horse employed for operating the machine, the harnessbeing further connected with a pole H set at an angle to the sweep andfastened to the same at its rear end.

The operation of the machine is thought to be apparent from theforegoing, and an extended description thereof is accordingly omitted,it being obvious that during the revolution of the sweep, the knife willslice a complete shingle from each block as it is brought into contacttherewith, the capacity of the machine being dependent upon the diameterof the bands, and upon the number of divisions into which the spacebetween the bands D and E is separated. It will also be understood thatthese spaced bands unite in forming an annular bed and that thedivisions of the space between said bands serve as seats arranged toreceive the blocks, these terms being employed in the appended claims.

lVhat is claimed is 1. The combination with a bed provided with anendless series of seats, of a horizontally revoluble sweep and a knifecarried thereby, the sweep being so mounted as to be capable of a freevertical'movement and means carried by the sweep arranged to engage theends of the pieces of work mounted in the seats to bring the knife intothe desired relation to the surface of said work, so that similarportions may be cut from each piece of work irrespective of variationsin the thickness of several of said pieces.

2. In a shingle machine, the combination with a bed comprising a pair ofconcentric annular members arranged in spaced relation to each other andthe space between being divided into a series of separate portions, theupper edges of the annular members in each portion forming a seat forthe work; a revoluble sweep; a knife carried by the sweep for engagementduring its rotation; and a holding device mounted in the spaces betweenthe annular members for each seat including a lever provided with aserrated work-engaging end.
